Most business success stories we read puts a spotlight on the origin story of the founders and their creation. But as engaging as the plot may be, there’s one side of the story that doesn’t get told too often: business documents.

This article aims to lay down all the important paperwork that you will need or come across as you’re running your business or corporation.

What are Business Documents?

It’s the general term used to refer to paperwork used during the course of a business’ lifetime. Here’s a quick overview of the 5 most important types of business documents.

Financial Documents – Used mainly for preparing budget proposals and filing tax returns. Typically prepared by the company’s accounting department.

Business Reports – These documents are created for the purpose of presenting information about a specific area of the business. For example: revenue reports, feasibility studies, market feedback, shareholder updates, and others.

Transactional Documents – Think invoices, order forms, and other documentation that serves as a means to acknowledge, confirm, initiate, and provide proof of a given transaction.

Part 1: Legal Requirements to Start a Business in the Philippines

Below are several legal documents that are required when starting a business in the Philippines.

DTI Registration for Sole Proprietorship

If you will be the only owner of the business, you have to register it as a sole proprietorship.

Under this type of ownership, the owner’s personal assets and liabilities are considered as an extension of the business.

It’s not protected from claims of outside parties since it’s not a separate entity. Sole proprietorships have to be registered with the DTI.

SEC Registration for Partnership

A type of ownership wherein there are two or more persons that share the capital and resources to build the business.

Any revenue generated will be split according to the agreement set amongst partners. Partnership-types of businesses have to be registered with the SEC.

SEC Registration for Corporations

As we’ve previously explained here, a Corporation is considered a separate entity from the owners of the business. It gives them limited liability in the event of a loss.

While it’s more costly to set up, this is one of the main reasons why corporations are established over Sole proprietorships. Corporations are required to be registered with the SEC.

Mayor’s or Business Permit

To properly establish the legitimacy of your business in a given area, you have to acquire a Mayor’s permit.

The following are the paperwork you need to submit in order to secure a Mayor’s permit:

  • DTI or SEC Registration

  • Location/Zoning Clearance
  • Building/Occupancy Permit
  • Fire Safety Insurance
  • Barangay Clearance
  • Public Liability Insurance

Note: Requirements may vary depending on the area or municipality where you’ll be setting shop so make sure to check with its City Hall for instructions.

BIR Registration

Prior to operation, every new business needs to register with the Bureau of Internal Revenue so the government can officially list the business in their book of accounts.

This needs to be done on the Revenue District Office where the business is registered.

They will provide the business’ TIN and BIR-approved documents likes official receipts and invoices, after all official fees and required paperwork have been submitted.

SSS Registration

A business that will employ any services or manpower to operate is required to register with the Social Security System.

An employer number will be assigned which is what the SSS will use in remitting employee contributions.


Similar to SSS, PhilHealth registration is also a requirement when establishing a business.

A PhilHealth Employer number will be assigned to the business which is what will be used to properly remit the employee deductions through the employer.

Pag-IBIG Fund

The Home Development Mutual Fund, or Pag-IBIG, is a government-owned fund that provides different types of housing loan options to its members.

When you set up a business, this is a mandatory registration.
